The coil 3 of each phase is configured at the periphery of resin that is the insulator 4 insulated with stator core 2.Insulator 4, in its periphery hold-in winding main body 31, is installed in tooth 21.
In the manufacture method of the stator 1 of this example, circumference (configuration direction) D rotated when being sequentially configured one by one by coil 3 is identical with circumferential opposite side C2.
As Figure 13, as shown in Figure 14, in the manufacture method of this example, use assembling fixture 5, this assembling fixture 5 has: moveable jaw portion 52, and it holds and rotates configuration coil 3B thus configure with opposed relative to the inner circumferential side of tooth 21; And the substrate clamp portion 51 of setting can be configured movably for this moveable jaw portion 52.Moveable jaw portion 52 has the handle part 521 supported the upper and lower conductor part 32C rotating configuration coil 3B, can be rotated, and can be slided relative to substrate clamp portion 51 by rectilinear guide by rotation axis portion 522 relative to substrate clamp portion 51.
In addition, be provided with 2 guide rails (guiding groove) 511 in substrate clamp portion 51, they are for the formation of the mobile route X of rotation configuration coil 3B when being configured at the tooth 21 of stator core 2.In addition, 2 rollers 523 being configured at 2 guide rails 511 are provided with in moveable jaw portion 52.
And, insert in operation in the first ~ four of manufacture method, when being made moveable jaw portion 52 slide by rectilinear guide, moveable jaw portion 52 while rotate 2 rollers 523 on one side move along 2 guide rails 511 centered by rotation axis portion 522, thus can make the handle part 521 in moveable jaw portion 52 move along the mobile route X rotating configuration coil 3B.And, the first ~ four can be carried out and insert operation thus rotation configuration coil 3B is configured to tooth 21.
In addition, in existing assembling fixture, make to concentrate the coil be wound around opposed obliquely relative to tooth after, carry out the Position Control of the moving part of 2 axles, thus by coil configuration in tooth.Therefore, when using assembling fixture repeatedly to carry out the assembling of coil, when assembling fixture changes the assembling position of coil, need, according to assembling position change, to revise the program etc. of the Position Control of the moving part of 2 axles.
On the other hand, in the assembling fixture 5 of this example, the substrate clamp portion 51 being provided with guide rail 511 can carry out the adjustment of position in advance relative to the installation portion installing substrate clamp portion 51.Such as, be inserted through in the structure of the screw of the through hole formed in substrate clamp portion 51 fastening relative to the screw formed at installation portion, the gap formed between through hole and screw can be made, larger than the gap formed between guide rail 51 and roller 523.Thus, even if when the assembling position change of coil 3, by adjustment substrate clamp portion 51 relative to the position of installation portion, the correction of assembling position also easily can be carried out.
Next, the method for tooth 21 and the action effect of this example that the coil 3 of 3 phases are configured at stator core 2 are described.
In this example, first, the insulator 4 of the final coil 3C of the tooth 21 being used for keeping finally being configured at stator core 2 is installed on tooth 21 (with reference to Fig. 8).And, by coil 3U, 3V, 3W of 3 phases of keeping in the periphery of insulator 4, sequentially configure (with reference to Figure 12) at each tooth 21 of stator core 2 around circumferential D.
As shown in Figure 8, initial configuration can not disturb the coil 3 of other adjacent phases in first coil 3A of the tooth 21 of stator core 2.Therefore, the inner circumferential side of the tooth 21 of first coil 3A and stator core 2 is just right, to move to outer peripheral side relative to radial parallel state, thus can be installed on tooth 21.But in this example, from simplifying the viewpoint of assembling fixture 5 used, with described later, first coil 3A rotates that to configure coil 3B identical, carry out the first ~ four insertion process configurations in tooth 21.

Like this, coil 3A, 3B, 3C of 3 whole phases are configured relative to the tooth 21 of stator core 2.
In addition, as shown in Figure 12, in stator core 2, for each coil 3 of the homophase cooperatively interacted an end 33A and the other end 33B, form each end 33A of neutral point 34, form each the other end 33B of wire portion 35, can carry out welding thus engaging.
Like this, for the first ~ four insertion operation, for first coil 3A and whole the carrying out successively rotating configuration coil 3B, by whole rotations configuration coil 3B, be sequentially configured at each tooth 21 of stator core 2 around circumferential D.In addition, all rotate configuration coil 3B and nondeforming can successfully be configured at tooth 21.
Therefore, according to the manufacture method of the stator 1 of the electric rotating machine of this example, initial configuration can be configured coil 3B in first coil 3A of tooth 21 and whole rotation, nondeforming successfully be configured at tooth 21.
In addition, by rotating the collocation method to stator core 2 of configuration coil 3B, each end 33A interference rotating configuration coil 3B can be easily prevented to be configured at the coil 3 of other phases of tooth 21.In addition, by the method for this configuration, between the coil 3 of 3 phases, the forming position of an end 33A and the other end 33B need not be made to offset vertically.Therefore, it is possible to reduce an end 33A of the coil 3 of each phase and the other end 33B from the outstanding amount of the axial end 201 of stator core 2.
In addition, the bending shape of an end 33A of the coil 3 of each phase can be pre-formed before being configured at stator core 2.Thus, the processing of the bending of the coil 3 being configured at stator core 2 etc. is not needed.Therefore, even if this reason, an end 33A of the coil 3 of each phase and the other end 33B also can be reduced from the outstanding amount of the axial end 201 of stator core 2.
